New Caledonia Expedition: An Army of Giant Parrotfish

Today we dove at Astrolabe Reef, a remote coral atoll northeast of New Caledonia. So far it’s the best place we have explored.

In our dives today we’ve seen everything one hopes to see: sharks, groupers, Napoleon wrasse, bright red old sea fans, and many other gorgeous animals. But the most impressive sight – and one that we will remember for a long time – was a school of 75 bumphead parrotfish (Bolbometopon muricatum). They are the largest of the parrotfishes, with a maximum length of 130cm and can weigh up to 50kg! The bumphead parrotfish is a vulnerable species, and a great indicator of fishing pressure: they are one of the few species to go away when people start fishing a reef.

This is why we are so excited and happy today, because we know that Astrolabe is still a pristine reef full of large animals. This is the most precious jewel we have explored in the last three weeks.
